/** The minimal static system prompt every node launches with — a thin launcher
 *  frame keeping the `\n\nGuidelines:` anchor the `before_agent_start` substrate
 *  hook (canvas-doc-substrate.ts) splices its `<memory kind="preference">` block
 *  before. ALL runtime/spine/lifecycle/kind prompting now lives as gated builtin
 *  memory docs (src/builtin-memory/), spliced in fresh every turn — this scaffold
 *  must never duplicate that prose. Imported by launch.ts (its own systemPrompt)
 *  and `sys prompt-review` so the two can never drift. */
